After sales follow up is really nice. I like when a company cares.
I would, however, limit this after sales service to one form of contact in the first week – and then perhaps a follow up call a few months down the track.
A phone call, an SMS and an email is probably overkill.
It’s as true for churches as it is for mechanics (and guys chasing a second date).
Don’t be too nice, or too keen to see me again. You’ll only freak me out.
